function hello(name){console.log('Hello,'+name)}

Basic whitespace/comment minifier. For advanced optimizations (dead code, mangling) use a build-time tool like Terser.

How to use JavaScript Minifier

Does it obfuscate the code?

No — it only removes whitespace and comments. For obfuscation, use a dedicated obfuscator.

Is the JavaScript Minifier really free?

Yes — every tool on ToolFlexPro is 100% free with no signup, no watermarks and no daily limits.

Is my data safe?

Everything runs directly in your browser. Nothing is uploaded to a server, so your data stays private on your device.

Does it work on mobile?

Yes. ToolFlexPro is fully responsive and works on any phone, tablet or desktop.

Do I need to install anything?

No installs. It runs instantly in any modern browser (Chrome, Safari, Firefox, Edge, Brave).
